Okay, so this is a d to a converter.
00:02
So on the left, we have a digital signal coming in with the least significant bit at the top, most significant bit at the bottom.
00:12
All right.
00:12
And then it comes into the minus input of this op -amp, creates a voltage output.
00:18
So the point is that these voltages, if they're on, are all the same.
00:27
It depends on which particular one is on or which ones that determine what our v out is.
00:38
But in general, all of these are the same if they're on or zero if they're off.
00:48
All right.
00:48
So as far as least significant bit, let's remember what that means.
00:52
As far as a binary number, this labels what they're.
01:04
So we can represent a number from zero.
01:08
To 63 depending on which one of these we turn on.
01:13
And that depends on that input binary number...
